The professional social media network was down, then up, then down again Wednesday morning.

LinkedIn, the professional social media network, is suffering intermittent service disruptions Wednesday morning.

Frustrated LinkedIn users began airing their grievances on Twitter before the start of the regular East Coast business day. Shortly after 8:30 a.m. ET on Wednesday, LinkedIn posted an update on Twitter saying, "We're aware the site is currently down, and our team is working on it right now. Stay tuned."

A variety of third-party web tracking tools also reported LinkedIn was experiencing a service disruption. www.DownRightNow.com reported that LinkedIn was down beginning just before 8 a.m.

At around 8:50 a.m. ET LinkedIn reported that the issue had been resolved. "The issues you may have experienced with our site earlier have been cleared," the company posted on its official Twitter page.

Then, about a half-hour later the site went down again, which LinkedIn again confirmed. "Our site is experiencing some issues. Our team is continuing their work on this. Stay tuned."

All in all, in less than a two-hour period the LinkedIn site appears to have gone down for about 45 minutes, went back up for about 30 minutes and then had a second service disruption.

Earlier this week Google Drive confirmed that a "significant" number of users were impacted by a service disruption on Monday. About 30 minutes later Google said the issue had been mostly resolved, but some users continued to complain about outage issues.
